Would TMPG competitors be able to carry ballast? A ton of weight in my truckbed puts me at a decent 54.4 TMPG.
I'd win the TPMG competition towing my camper. 14,400 pounds total weight and 10 mpg shoving it up mountains as hard as I could without any regard for FE; I'm sure I'd get 12mpg now unless it was 100% stop-and-go. That's 86 TMPG by your calculator... |
If I stop by the quarry before I leave town I can get a ton of bluestone gravel in my pickup truck for $10... ;)

The weight on the registration may have been GVWR (maximum legal weight with a full load), not curb weight. Many states (mine, for example) do it that way.
Perhaps a nearby truck scale (truck stops, gravel yards, landfills, transfer stations, some trucking/multimodal hubs), or the police/DOT, would be willing to help weigh the heavier vehicles? My VW would come in at a respectable 66 TMPG with a full tank of gas and if I squeezed 40 MPG out of it (not my best record but tough for me to achieve on my commute). |
I drove over the scale where I take my aluminum cans for recycling. The Excursion went over the scale at 7900# with less than 3/4 of a tank of fuel. LOL! At least it's lighter than the bus was.
Does make my ton miles per gallon better than our Focus. :D |

My Jeep Liberty CRD went over the scales at 4550#...on the highway (100%) I can get 28+...What would be my TMPG at 28mpg?
|
According to the calculator it it is 63.7 TMPG

Not sure if you guys saw the results of the 2nd one or not: https://www.icerace.com/amec-2008-economy-2.html
The first one was for fun before a picnic, the 2nd one brought out some hardcore drivers. The Prius and the diesel had over 100 ton mpg. That Avenger that won last time at 48MPG I was sure was a filling fluke but he got 50MPG this time, so that's amazing, he needs to start a gaslog. As for the route, it's sweeping curves with lots of ups and downs in the Adirondacks. The only lights are at the end we pass a stretch of 6 or so in 1-2 miles. That sucked. But there was also a section of probably almost 30 miles all with either a steady or slight downgrade. I'm sure most didn't have their engines on for a long time. I rode with my friend in his RX7, we got the worst MPG and the fastest course time! But mostly we tuned up his MegaSquirt a bit and had a fun time. It's really funny because I have a Festiva that can average 50MPG and he has an CRX HF (as well as a VX) that easily pulls 55MPG and we probably could have gotten really close to the 65MPG needed to win. |
A measure of efficiency commonly used in the aerospace industry is "seat miles per gallon". I think to factor in weight, we need to compare "actual payload-mile/gallon".
i.e. examples: If you drive a 5800# SUV, get 13 mpg, and normally drive by yourself at say 200#, thats 2600 payload-lb-miles/gallon. Weight of vehicle shouldn't matter, it's the weight of the payload carried that matters. On the other hand, if you filled all 9 seats with 220# passengers, and manage 12 mpg, you get 23,760 payload-lb-miles/gallon. A motorcycle at 70 mpg with a 170# rider would be 11,900 payload-lb-miles/gallon. A 12 passenger Dodge Sprinter Diesel full of 200# passengers at 26 mpg would net 62,400 payload-lb-miles/gallon. just my .02 :) |
